Abstract (en)
[origin: EP3852288A1] This application provides a power indication method and apparatus, relates to the field of communications technologies, and is used to enable a network device to perform, in real time, power control on a terminal for uplink transmission. The method includes: A terminal generates antenna transmit capability information, where the antenna transmit capability information is used to indicate whether a maximum transmit power value of each transmit antenna port of the terminal reaches a preset power value, or the antenna transmit capability information is used to indicate a maximum transmit power value of each transmit antenna port of the terminal. Then, the terminal sends the antenna transmit capability information to a network device, so that when scheduling uplink transmission, the network device can determine whether the maximum transmit power value of each transmit antenna port of the terminal reaches the preset power value.
